The name 'Pesach' is also said to have been picked up from the fact that it was the name of the sacrificial lamb that was made in the Temple on this holiday before Exodus. Other names for this holiday are 'Chag he-Aviv', which means 'the Spring Festival', 'Chag ha-Matzoth', which means 'the Festival of Matzahs' and 'Z'man Cherutenu', which means 'the Time of Our Freedom'. The holiday is observed for eight days and Seder is observed on its first two nights. The Fast of the Firstborn is observed on the day before Pesach, which is a minor fast for all firstborn males to commemorate the fact that firstborns of Israelites were saved during the slaying in Egypt. Passover is a time for family gatherings and happiness for Jews as it signifies that they are finally free and are their own masters.
